With the inauguration just two days away, Comedy Central did a search of their archives to find out who was the first stand-up comic to do a Barack Obama joke on their network. They found a clip of W. Kamau Bell on Premium Blend in 2005 talking about how Obama's name sounds too black to be president. Check out the clip.
I've been lucky enough to see this guy in person (and am going again next week) and he's outright hilarious. If you happen to be in the San Francisco Bay Area you can catch W. Kamau Bell's stand-up at The SF Playhouse through February 28th. http://www.wkamaubell.com/ for more info on show dates and times.
